TrueNAS SCALE can create persistent Linux ‘jails’ with systemd-nspawn. These containers are very similar to Jails from TrueNAS CORE or LXC, LXD and Incus containers on Linux. Jailmaker helps with the following: Setting up the jail so it won’t be lost when you update SCALE Choosing a distro (Debian…

If you already have a jail built and working, you’ll be fine. See further up where I discuss the upgrade path. If you need to create new one’s, see the post after on how to do that. There are some gotcha’s moving to EE, so read those as well. If you’re using nvidia, you need to install those driver…

TODO Add GPU attachment to containers. Integrate ZFS datasets or zvols into instance creation. NOTE: If you’re running this in a VM, you’re may run into Nesting issues. You need to configure your VM to nest from the host then it “should” work fine… The config options I added will load the need…

I’m going to break this out to it’s own thread since this is for the new jails moving forward. EDIT: Created a new thread here . Hopefully we’ll get some community involvement and testing as we move forward.

[image] dasunsrule32: I need to look into Incus more. I’m assuming it’s leveraging the kvm module in the kernel for VM’s and LXC for containers. explanation about incus [Docker in Incus is Awesome] i didnt know what it was, had to look it up

can explain how u got namespacing working? i would like to know

This is no longer needed in TNS 25.04… the old configs work again. To update the NVIDIA GPU enabled jails, you will need to disable the gpu and update still, but everything else works.

Hey. I just found this thread, and boy this is a lot of read and learn. I just transitioned from Core, and got the 24.10.2 installed on bare metal. Importing the old pool from Core to Scale was easy and all, but I can’t get my syncthing to work properly. If you don’t mind providing some directio…

Coming from CORE, I’m used to having a jail for each application (Plex, radarr, etc.). But it looks like the preferred way with SCALE would be to have a single sandbox and then separate docker containers within the single sandbox? Or is there a good article that discusses the overall layout/design o…

Solved: I’m on the lookout for a tutorial to migrate from jailmaker to instances (incus).
